The easiest way by ground is to take Amtrak, which runs between DC and Boston with stops in Philadelphia, Newark and Manhattan on an almost hourly schedule. To go a little bit faster look for the Acela trains, as these are the new "high-speed" trains. Don't know if there's non-stop air service between PHL and BOS.

I would probably say EWR or LGA. If you're going to stick to trains, EWR will be the easiest to get to. Try a booking engine that will check several area airports. For example go to Orbitz, click on "expand search options" and select the box to check airports within a 70-mile radius, then put in LGA or EWR. That should help you find the lowest fare between the 3 major NYC airports and your destination.
